0focal plane Z upper and cannot blur-free imaging in retina R).The configuration of offset lens 130 can compensate this effect, make to be first passed to again penetration display 110 and Focussing lens 120 by offset lens 130 from extraneous environmental images EM, and then make human eye HE clear view to environmental images EM (imaging in retina R as image strip EMB can know after by the compensation of offset lens 130).Thus, human eye HE can be in clearly observing the image IM of penetration display 110, and still can clearly observe the environmental images from context, and then can increase the interaction of user and environment, and the sense of reality and the image quality of lifting augmented reality (augmented reality, AR).In the present embodiment, offset lens 130 can be a biconcave lens, but in other embodiments, offset lens 130 also can be plano-concave lens or any lens person with the ability of dispersing, and the present invention is not as limit.
Fig. 2 A is the imaging schematic diagram according to first virtual image of the Focussing lens in the embodiment of Fig. 1.Please refer to Fig. 2 A, specifically, human eye HE can observe one first virtual image V1 corresponding to penetration display 110 by Focussing lens 120, and wherein penetration display 110 is between the first virtual image V1 and Focussing lens 120.For example, in the present embodiment, the focal length of Focussing lens 120 is f
1penetration display 110 is ds with the distance of Focussing lens 120, now human eye HE can observe by Focussing lens 120 the first virtual image V1 of the upright amplification of penetration display 110, and specifically, the lens center distance of the first virtual image V1 and Focussing lens 120 is image distance q
1=(ds+q), and object distance P
1for ds, again because of object distance P
1be less than focal distance f
1, gained is imaged as the first virtual image V1, therefore make image distance q
1for negative value, therefore object distance P
1with image distance q
1meet following formula:
In the present embodiment, in order to make human eye HE can observe by Focussing lens 120 the first virtual image V1 of the shown image of penetration display 110, therefore penetration display 110 is configurable must be very close to the focal distance f of Focussing lens 120
1within.And on the other hand, the distance dh of penetration display 110 and human eye HE can be less than the shortest visual range of human eye HE, human eye HE still can observe by Focussing lens 120 the first virtual image V1 of penetration display 110 upright amplifications, and wherein the first virtual image V1 and human eye HE are positioned at the different both sides of penetration display 110.
Fig. 2 B is the imaging schematic diagram according to second virtual image of the offset lens in the embodiment of Fig. 1.Fig. 2 C is the imaging schematic diagram according to the 3rd virtual image of the offset lens in the embodiment of Fig. 1.Please also refer to Fig. 2 B, in the present embodiment, environmental images EM can sequentially penetrate offset lens 130, penetration display 110 and Focussing lens 120 and image in retina R, in the time that penetrating offset lens 130, environmental images EM can form one second virtual image V2, the second virtual image V2 and environmental images EM are positioned at offset lens 130 homonymies, that is illustrate as Fig. 2 B, the second virtual image V2 and environmental images EM are all positioned at offset lens 130 side far away apart from human eye HE, so that human eye HE observes upright the second virtual image V2 dwindling of environmental images EM.Wherein, the focal length of offset lens 130 is f
2, the distance of environmental images EM and offset lens 130 lens centers is object distance P
2, the distance of the second virtual image V2 and offset lens 130 lens centers is image distance q
2, again because of object distance P
2be less than focal distance f
2, gained is imaged as the second virtual image V2, therefore make image distance q
2for negative value, therefore object distance P
2, image distance q
2meet following formula:
Then please refer to Fig. 2 C, in the time considering the effect of Focussing lens 120 and offset lens 130 simultaneously, now human eye HE can observe one the 3rd virtual image V3 corresponding to the second virtual image V2 by Focussing lens 120, and the second virtual image V2 and the 3rd virtual image V3 are positioned at Focussing lens 120 homonymies, that is illustrate as Fig. 2 C, the second virtual image V2 and the 3rd virtual image V3 are all positioned at offset lens 130 side far away apart from human eye HE.Wherein, in order to make human eye HE in watching the first virtual image V1 of penetration display 110, also still can keep the relative distance sensation with context, in other words, user, in the time using head-mounted display apparatus 100, still can be watched large small distance and do not worn the environmental images EM being more or less the same before head-mounted display apparatus 100 by Focussing lens 120, penetration display 110 and an offset lens 130.That is, the image space of the 3rd virtual image V3 is with in fact environmental images EM existing position in space is very close for human eye HE, in the present embodiment, the distance of the 3rd virtual image V3 and human eye HE and with in fact the distance of environmental images EM and human eye HE can be in a scope, to make the human eye HE can be in the case of not affecting the distance perspective of context, utilize Focussing lens 120 to watch the shown information frame of penetration display 110, and the volume of head-mounted display apparatus 100 can reduce by this, and still can have good image display quality and can sacrifice user to arround distance perspective.For example, in the present embodiment, the image Size Error scope taking 10% is as example, and in the time that the distance range of environmental images EM and human eye is 90 to 110 centimeters, the distance range of the 3rd virtual image V3 and human eye HE is 90 to 110 centimeters; In other words,, in this scope, the error of the image size of the viewed environmental images EM of human eye HE, in 10%, and can be observed the shown information frame of penetration display 110 simultaneously.
More specifically, in order to reach this object, the focal length relation of Focussing lens 120 and offset lens 130 can be as shown in the formula design:
Wherein α is error parameter, and 0.9 ≦ α≤1.1.If environmental images EM is for example, during apart from human eye HE not far (in the present embodiment, distance is less than 250mm), the focal distance f of offset lens 130

1the absolute value of ratio be less than 1, that is the focal distance f of offset lens 130
2be slightly less than the focal distance f of Focussing lens 120
1.By this, human eye HE can use head-mounted display apparatus 100 to watch the image of the shown image of good penetration display 110 and environmental images EM in the such as indoor nearer area of context of waiting.But if environmental images EM is for example, during apart from human eye HE far (in the present embodiment, distance is more than or equal to 250mm), the distance d between offset lens 130 and Focussing lens 120 is with respect to the object distance P of the second virtual image V2
2and image distance q
2very little and can ignore the now focal distance f of offset lens 130
2focal distance f with Focussing lens 120
1the absolute value of ratio approach very much 1, can simplified design in practical application and by the focal distance f of offset lens 130
2the focal distance f of design and Focussing lens 120
1identical.By this, human eye HE can use head-mounted display apparatus 100 to watch the image of the shown image of good penetration display 110 and environmental images EM in the such as outdoor wider area of context of waiting.Further, in the present embodiment, the focal distance f of Focussing lens 120
